Intel has added two new desktop processors to its Core Ultra 200S Plus series. Core Ultra 7 270K and the Core Ultra 5 250K are both part of the release. The 200S Plus series is an update to the Core Ultra Series 2 CPUs. It has certain hardware changes compared to the 200S variants that came before it.

Intel says that the Core Ultra 7 270K is the fastest gaming desktop processor it has ever made. The announcement also discusses modifications to the architecture, improved memory support, and a new optimization tool that will improve performance across a range of workloads.

The Core Ultra 200S Plus Lineup

This lineup includes two new Intel processors. Core Ultra 7 270K is a new version of the 265K, and the Core Ultra 5 250K is a new version of the 245K.

Both CPUs now have four more efficiency cores than the ones they replaced. Core Ultra 7 270K has eight performance cores and 16 efficiency cores, which is more than the 265K's 12 efficiency cores. Core Ultra 5 250K now has six performance cores and twelve efficiency cores. 245K has only 8 efficiency cores.

There was no mention of clock-speed adjustments; thus, the Core Ultra 7 processor's boost frequency should remain at 5.5 GHz.

Improvements in Die-to-Die Frequency and Latency

Intel also noted that the die-to-die communication frequency has improved. The business said that the CPUs can reach up to 900MHz at the connection frequency.

The connection connects the CPU cores to the built-in memory controller. Intel said that higher frequencies speed up communication within the chip, lowering latency and improving gaming performance.

Claims About Gaming Performance

Intel said that the Core Ultra 7 270K can run games up to 15% faster than the previous model.

The result is based on testing 38 games. The company calculated the average frame rate across all 38 titles. It used that figure to estimate a performance boost of up to 15%.

More testing will show how well the CPU performs with different gaming engines and in real-world scenarios.

How well it Works with Many Threads Compared to Ryzen

Intel also looked at the Core Ultra 5 250K and the AMD Ryzen 9600X side by side. The business says that in some testing, the 250K performs up to 103% better with multiple threads.

The 3D Mark CPU Profile Max Threads test was chosen as the standard for comparing productivity. The results show how additional efficiency cores might affect workloads that use multiple threads.

But the benchmark only measures how well threads scale, not how well full-productivity workloads perform. To determine how well the system performs in the real world, additional testing will be needed.

Support for Memory and Compatibility with Different Platforms

Core Ultra 200S Plus series increases the maximum memory speed from 6400 MT/s to 7200 MT/s.

The processors also work with the 200S Boost BIOS configuration and are still compatible with motherboards that use the 800 series chipset. There is no need to modify the socket; users can install the processors on compatible systems without replacing the motherboard.

Intel also added early support for four-rank CU-DIMMs. These modules can hold up to 128GB of data each.

Intel's Binary Optimization Tool

Intel released a new software tool called the Intel Binary Optimization Tool. The tool changes built workloads to boost instructions per cycle and speed up performance.

The tool can improve performance even if it was designed for older x86 processors, game consoles, or other CPU architectures. Testing will show how the technology changes the performance of games and other tasks.

Final Thoughts

Intel said that both processors will be available on March 26. Core Ultra 7 270K will cost $299 at launch, $100 less than the 265K's debut pricing. Core Ultra 5 250K will cost $199 when it comes out. There will also be KF versions of both CPUs, which don't have the built-in graphics unit but keep the same core configuration and speed.
